RESUMO
Rhinosporidium seeberi causes granulomatous inflammation of mucocutaneous sites, presenting most frequently as polypoidal lesions in the nose. Sites like the conjunctiva, trachea, nasopharnyx, skin, and genitourinary tract are less frequently involved. Primary cutaneous lesion is extremely rare. We report the fine needle aspiration cytology (FNAC) of rhinosporidiosis occurring as a primary cutaneous lesion. FNAC of polypoidal and warty skin growths on leg in a 28-year-old male revealed numerous sporangia and spores of R. seeberi. There were no mucocutaneous lesions. Histopathologic examination confirmed the diagnosis. Globular bodies in endospores of R. seeberi are specific; their demonstration confirms diagnosis of rhinosporidiosis. FNAC or scrape cytology is economical and reliable in preoperative diagnosis of suspected and unsuspected cutaneous lesions of R. seeberi.

Adenoid cystic carcinoma is a malignant tumor of the salivary glands. It is slow growing and is characterized by the delayed development of distant metastasis, which may develop even a decade or more after initial treatment of the primary tumor. We present the case of a 68-year-old male with complaints and radiological findings suggestive of primary hepatocellular carcinoma. However, fine-needle aspiration findings showed metastasis of adenoid cystic carcinoma. A retrospective clinical and ultrasound examination of the patient revealed a small asymptomatic enlargement of the submandibular salivary gland that was aspirated and showed features of adenoid cystic carcinoma.
